(y+1)/5 + (2y+1)/2 = 1
Multiply through by 10 (= hcf of 5 and 2)
2(y+1) + 5(2y+1) = 10
2y+2 + 10y+5 = 10 ie 12y = 3 or y = 1/4

The answer is 1/2. If you do this long hand the 4.2 goes inside the bracket and the 8.4 goes outside. When you divide start by moving the decimal over one place on both numbers. When you divide you get 0.5 which is equal to one half.

420here are the steps to find your answer. I am explaining this as if you were using a division "bracket."6 goes into 25 4 times with a remaining 1bring down your 26 goes into 12 2 times with a remaining 0bring your other 0 down6 goes into 00 0 timesThis gives you an answer of 420.
It is impossible to read exactly what the expression is - it looks like there are some operators missing from expression: between the 2 and 5n, between the 5 and n, between the 3 and n. As written it looks like: 25n + 3 + 5n + 3n + 2 = 33n + 5 which is not divisible by 17 for n = 1 (at least). Please re-ask your question spelling out every operator, eg 2 bracket 5n plus 3 close bracket plus 3 minus n...

No. If you are dividing the number that is getting divided in in the brackets. ex. 3 divided by four is (3)4
Look for something which you can divide both terms by. In this case both 3x and 15 are divisible by 3, so put this outside of a bracket and write the two terms divided by the common factor inside the bracket. So the answer is 3(x+5).

27 divided by (2 x 5 -7) = 27/10-7 =27/3 = 9
This is a case where we can apply l'Hopital's rule, separately calculating the derivatives of the numerator and denominator, then take the limit using those: Limx→2 [(6 - x)1/2 - 2] / [(3 - x)1/2 - 1] = Limx→2 [1/2(6 - x)-1/2 (-1)] / [1/2(3 - x)-1/2 (-1)] = Limx→2 (3 - x)1/2 / (6 - x)1/2 = 1/2
All you have to do is put ur number in and upside down division bracket and if it it a composite number you divide by a prime number and then if the number is even like 84 the you put 84 in the upside down division bracket and it can divide by two so the you put the number 2 to the left of or upside down division bracket and the underneath it you put you put your answer which is 42 because 84 divided by 2 is 42 abd then 42 is still even so divide by 2 and it will be 12 because 42 divided by 2 is 12 then it is still even so keep dividing by 2 and you will get 6 because 12 divided by 2 is 6 still even so divide by 2 and you will get 3 because 6 divided by 2 is 3; 3 is a prime so you can stop
When dividing 3 by 39 using long division, you would place the 3 outside the division bracket and the 39 inside the bracket. The first digit of the quotient would be 0, as 3 is less than 39. You would then add a decimal point after the 0 and bring down a zero to continue the division process. The result would be 0.076923 (repeating).

Spaces are not 'marks,' but they are nevertheless the most common form of punctuation. The Romans did not put spaces between words, and divided words at the end of a line without using any punctuation mark. A nightmare!
